AMONG SHEEP IN NEW SOUTH WALES.

rest the head on the hurdles, evidently appearing to suffer much 
pain. The respiration becomes more laboured, and a cough is 
also occasionally perceived. 
The disease now advances to the third and last stage, in which 
the interior of the nostrils exhibits the highest state of inflamma- 
tion (some parts displaying a leaden hue), and extending to the 
frontal sinuses ; the secretion from the nose becomes lessened, 
very thick, and occasionally streaked with blood. The nostrils 
appear obstructed by the matter collected about them, occasioning 
a very laboured respiration. The animal now prefers lying 
down, and rests the head upon the ground; there is sometimes 
a troublesome cough ; but a cough is found to prevail even in the 
animals recovering from the disease, and yet in many, again, the 
cough is not at any time observed as a symptom. The eye 
becomes glassy ; the animals appear stupid, and unable to direct 
their steps; if permitted to leave the fold, they walk against a 
tree, or into a water-hole. 
This stage may be considered as fatal ; and as death advances, 
irregular but voluntary movements frequently continue ; thq 
appearance of dulness and stupor is increased, and there is 
a general diminution of sensibility. A general trembling is 
now observed in the animal, more especially in the fore extre- 
mities ; it kneels down, remains for about the space of a minute 
in that position, falls down comatose, and after repeated struggles, 
and sometimes with a very laboured respiration, expires. 
The length of time occupied by the disease in running 
through its different stages, or the intervals of time which elapse 
between each stage, varies. In some of the sheep attacked by 
this epidemic death has occurred in six hours after the first 
appearance of the symptoms ; sometimes in twelve hours, and 
sometimes the animal lingered on until the third day : if he lived 
beyond that time, he usually recovered. 
It has been remarked, that in second and third stages the 
nostrils and face are much swollen; there is also a tumefaction of 
the lips, and in many I have observed an enlargement of the sub- 
maxillary glands. In some of the sheep the discharge was only 
observed to proceed from one nostril, in the first and second 
stages; but in the third stage the discharge has flowed from 
both ; the animal at the time usually inclines its body to the 
side whence the discharge proceeds ; the highly inflammatory 
state of the nostrils is as much observed in this, as in that form of 
the disease in which the discharge proceeds equally from both 
nostrils. 
A favourable prognosis may be formed when the animal com- 
mences eating, raises its head, and appears more lively ; all these
